applicano ned May 15. 1905. sum1 No. 260,392.

To all whom ,it may concern:

Be it known that I, AifroN HOPKINS, a citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Im rovements in Adjustable Electroliers; vand Ydo declare the following to bc a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accom anying drawings, and to the fiigures of re erence marked thereon, which `orm a part of this specification.

My invention relates to im rovements in adjustable electroliers, my o ject being to still furtherimprove the construction set forth in n1 f application Serial No. 251,899, filed Marc 24, 1905.

The invention will now be described in de-V tail, reference bein 1' made to the accompanying drawin rs, in w lich is illustrated an embodiment t iereof.

In the drawings, Figure 1 is a vertical section of the device. Fig. 2 is a sidc elevation showing the outer casing in section. In Fig. l the outer casinr is omitted. Fig. 3 is a fragmentary detai View illustrating the manner of connecting one branch of the internal The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate an outer casing, within which is located a depending framework 6, suitably attached. to the ceiling of' a room or other suitablegsupport. Journaled on the support is a drum 7. Theeupport carries an axle 8, through which passes an electrode 9, connected With a branch 10 of the external circujt. This electrode is surrounded by insulating material, with which the stationary axle 8 1s provided. The electrode 9 is engaged at its inner extremity, by a Spring-contact 12, mounted on a binding-post 13, with which a branch 14 of the internal circuit is also connected. The other branch 16 of the internal circuit is connected with an electrode 16, located in line with the axis ofthe drum and rotatin with the latter. The electrode `16 is surroun ed by insulating material 17, the latter being inciosed bye metal sheath 18, jgnrnaled in the framework 6. The outer extremity of the electrode 16 is engaged by a stationary spring-contact 19, whose extremity remote from the electrode is connected with the branch 10 of the extern circuit.

The conductors 14 and 15 of the interrn circuit are passed around the drum and lead downwardly to a lamp 20, passing between uide-rolhrs 121 and 22, mounted on the rame i Attention is called to the fact that the drum is spring-actuated or spring-held.

`From the foregoin description it will be seen that the electro e 9 is stationary, while the spring-contact 12 rotates with the drum and engages the inner extrc1nity,of the electrode, thus conncctin the branch 14 0f the internal circuit with t e branch 10 of the external circuit.. It will also be understood that the electrode 16 rotates with the drum and is directly connected with the branch 15 of the internal circuit, wh-ile its outer extremity engages a stationary sprin -contact 19, whose extremity remote from t c electrode is connected with the branch 10". of the external circuit.

I claim- In an adjustable clcctrolier, the combi` nation with a suitable stationary sup ort, of a spring-actuated drum journale on said support, internal circuit -conductors mounted on the drum, two electrodes, one being mounted to rotate with the drum and the other being stationary, both electrodes being in line w1th the axis of the drum, the stationaryelcctrode being directly connected with one branch of the external circuit, a fpring-contact mounted to rotate with the rum, for connecting the stationary electrode with one branch of the internal circuit, the rotary electrode being directly connected with the other branch of the. internal circuit, and

a stationary spring-contact for conne ting theV rotary electrode with` the other branh o the external circuit. i

In testimony whereof I afx mjteignaturd in presence of twowitnesses. '1
